D8H engine stuck

[RStecik]

Morning. Started lurking on this forum and I have got to say you guys have a wealth of information. I’m wondering if anyone has any experience with a low serial number D8H engine getting stuck from sitting. (Ran when parked, sat for about 9 years)

Also any ideas where to find parts in the great white north? I’ve found considerably better prices on parts in the States but no luck on places in Alberta.

Thanks

how old exactly is that 8? have had some exp years ago getting one going after it sat and locked up what i did then worked

Actually just got the serial number ran and found out it’s a 1964 model. Old brute with an open stack unfortunately. Interesting thing is the pony motor has been removed and converted to a 12v starter. And thanks for the reply.

wow it was 1967 that i did the one i mentioned.it must have been a 59 or 60 as it still had the pony` it would`nt run either. i spent 6 days working on that thing on a bet from the owner that i could not get it running was a lot of work but it did run. had to remove both intake and exhaust manifolds and valve covers , i then blew out as many holes as i could get air into with a 200 cfm compressor then soaked it down through all the it&ex valve holes with a mix of kerosene&10wt motor oil. then went to work on getting the pony motor started and running good enough to crank it. there is more to this story but not tonight

Post it up when you feel like it. It’s great to hear stories of wrestling old iron back from the dead.

Kinda wish it still had the pony motor. The heat and vibration would probably help quite a bit.

I have one of those (D8 46A). did I understand that the exhaust was uncovered? if it was, you are in for a lot of work. if rain got in , you will have to remove the turbo and then the exhaust manifold and see where the water got into. I usually get whatever I need from Finning or Union Tractor. what part of alberta are you in?

 

[RStecik]

Well that sucks. Kinda figured I was in for a bit of wrenching. I’ve talked to finning and Union. Was just seeing if there were any other suppliers around. I’m up near high prairie.

I'm between falher and Rycroft. is yours a 36A or a 46A ? my 46A is a 1965 vintage with pup engine start. are you sure its a 12 volt and not 24? you may have to read the plate on the starter to find out. I think the pup engines were all on the low horse H and electric optional on the high-horse.

I think if you've had water down an uncovered chimney you're in for a bit more than just the removal of turbo and exhaust manifolds. I can see the heads having to come off as a minimum TBH. If you have the capacity to do it why not bite the bullet now. Snatch the engine complete and get it into a shed/shop where you can reduce it to its component parts..? Because you might well end up doing that anyway if you start removing parts piecemeal from the engine with it installed in the tractor, and so end up doing a load of hard work when it could have been done a lot easier.

 

[RStecik]

Hey Nige I’m thinking it’s going to be an interesting project. Gotta try something first to hopefully free it up.

This machine used to have a put motor but has been converted to electric. The starter clearly says 12 volt on it. I looked because I thought it was strange as well.

By northern Alberta standards that makes us practically neighbours 56

46A with the power shift.

The argument for getting it running first is to know if the transmission etc works. If you know the history personally, or from somebody you trust, there's still the possibility of what happened in the meantime. If "it ran when parked" is the story from the seller, then I'd be especially suspicious of putting any money into it before it runs and operates.

Before even trying to break it loose, drain the antifreeze and see what's there, then loosen the engine oil drain plug enough to get several drops to see if it's oil, water, or antifreeze. Then figure out the next step.

Make a bar starter. See if you can't bar it over to free it up. Just a suggestion as i have never tried this method But given certain circumstances, I would give it a whirl. At least this would get the rotating assembly free again.

 

[StanRUS]

Frozen 36-46A D342 engines: 1st loosen oil drain plug and drain out anti-freeze coolant-water. 2nd remove injector nozzles and pour ATF WD-40 into each cylinder and let sit for a couple days. 3rd loosen exhaust manifold nuts so manifold has a gap between cyl head and manifold flange. THEN try to rotate the engine manually by hand. You can remove the cover located on top of the bellhousing (4ea 3/8" capscrews) and timing pointer; use a bar to engage the starter-flywheel teeth. OR remove the starter and use a bar (or Cat turning tool-make from starter nose) to manually 'try' to turn the engine.
Leave injector nozzles out, install starter motor and try spinning over the engine.
Good luck

I’d try the bar starter method but I don’t have access to a starter I can mangle. So what I’m gonna try is tightening the poop out of the fan belt then strapping a bar to the fan blades. I can get her to rock about a 1/4 inch so I think if I can do that a thousand times it should break free

You'll also probably have arm muscles like Garth by the time you're done. Best of luck, but as Stan said above, get some lube down into the cylinders in advance to get things well soaked and give yourself the best chance.

 

[RStecik]

I’ve poured a bunch of smoo down the exhaust. Logic being that if that’s where water has gotten in the oil should get in there too. Should charge a membership fee to get people to come out and try. People pay to go gym and lift heavy things

 

[Nige]

Those same people are probably like Jethro from the Beverly Hillbillies - not much up top but good at lifting heavy weights.

 

[Dave Neubert]

You probably wont free it up using the fan pull the starter and use a bar and pull the injectors and pour some lube down the openings

 

[8k bill]

If its been sitting for 9 years and water has got in I highly doubt that you would free it up. As Nige said I would wip the heads of and have a look and make an assessment whether to carry on. Whatever you do it's going to be a fairly big job so tool up and good luck. Bill

first pull the dip stick and see if the oil level is in normal range and then crack the drain plug and see how water comes out, and then you will know how much water got in. then you will know how much work you getting into
